Based on https://privacytests.org
Desktop browsers in their current stable versions, sorted from better (left) to worse (right). These are:
Librewolf, Mullvad, Brave, Tor, Safari, Chromium/Ungoogled, Firefox, Edge, Opera, Vivaldi, Chrome.
Note: Each test is counted with a value of one in this chart, however each test may not have an equal importance in regard to privacy. It still gives an image of which browsers value privacy and which do not.
The maximum (worst possible) score is 143.
Edit: Also FUCK BRAVE. But for other reasons than these points. Read the description before you vote or comment ffs…
How? Firefox 121 has that score because it “failed” on 86 of the 143 tests, you can see which tests if you go to the source.
As someone already commented, Firefox actually lets a bunch of things through and has telemetry. But it can be hardened and it is (IMO) the best browser all-in-all.
But it is not perfect.
Please note (AGAIN) that 1 test (1 point) here is NOT equal to all other tests. But I have no way to weigh one test against another, there are 143 tests (points) to consider. I thought it was obvious but for some reason people chose not to read the description, or misunderstood it. Sorry if it wasn’t clear enough.
I appreciate your effort in doing the work and putting the chart together :)
You fairly disclosed how it was all generated, but sadly not everyone will read that. A lot of people are going to look at that chart and their conclusion will be “Wow, Firefox is like a tenth as private as Brave!” - which you and I both know is not a true statement at all.
Even if people did read it, things get saved and shared out of context all the time, and before you know it this chart is going to pop up in some Discord argument as evidence for why Firefox sucks just as much as Chrome, completely divorced from your comments or any reference of where the data came from - the source website URL isn’t part of the image either.
I guess that’s the danger of visualisations. Data Viz can paint a complex picture clearly in an instant, we just have to make sure its painting the right one.
